tion, through which it passes. It has a temperature of 50 degrees 

 Fahrenheit. 



Utilization 



Xo spring deposits occur in the immediate vicinity of Giant springs. 

 The water is not generally regarded as possessing therapeutic qualities. 

 It is not utilized at present, but is allowed to empty into the river, ma- 

 terially increasing the flow of the stream. There are. however, a few 

 improvements, such as sidewalks, etcetera, which make it possible for 

 tourists to view the springs from the most advantageous points. "\^Tiile 

 no use is now made of this large volume of water, it is so situated that 

 the water could be pumped if necessary to a standpipe in East Great 

 Falls, from which it could be easily distributed to any part of tlie city. 

 Tiiis, liowever, will probably never bo done, for water for city supply can 

 l)e more economically obtained from ]\Iissouri river, a short distance aliovc 

 the town, where the present water works are located. With the develop- 

 ment of M'ater power at the Falls of Missouri river below the Springs, 

 and the growth of industrial towns which would necessarily accompany 

 such development, the water of the Giant springs would afford an excel- 

 lent source of domestic supply. 



Co:mposition 



A chemical analysis of the water was made some years ago by Pro- 

 fessor James A. Dodge, of the University of Wisconsin, and a field 

 analysis was made during the past field season by W. E. Calvert, of the 

 United States Geological Survey. These analyses are given below:
